Sharkbite UAB058LFA Barb Pex-a Brass Coupling

Product Description

The SHARKBITE UAB058LFA is a barb-style PEX-A brass coupling designed for joining PEX-A tubing in residential and light commercial plumbing systems. This fitting uses a barb connection method, which requires a crimp or clamp ring tool to secure the PEX tubing over the barbed end, creating a reliable, leak-resistant joint. Constructed from brass, the coupling offers durability and corrosion resistance suited for potable water supply lines. Licensed plumbers and experienced piping contractors are the primary installers of this type of fitting. It weighs 0.127 pounds, making it a compact, lightweight component for rough-in and repair work.

This coupling is used in residential plumbing rough-in, remodel, and repair applications where PEX-A tubing runs require a straight connection between two pipe sections. It is sold individually, making it practical for both single-repair service calls and larger installation projects requiring precise quantities. The barb design is compatible with standard PEX-A crimp and clamp installation tooling commonly carried by plumbing professionals.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before cutting into any existing line. A dedicated PEX crimp or clamp ring tool is required to properly seat the barb connection and compress the ring to manufacturer specification. Do not attempt to install barb fittings without the correct tooling, as improper installation can result in joint failure.
